I have my friend's laptop, and we managed to get AVG downoaded before anything too bad happened I think...(no, his antivirus was not up to date). Clicked the wrong button and whammo! Anyway, AVG cleaned a lot up, and the computer is running fine now, but I get two runDLL error windows pop up every time I restart, and AVG has stopped a couple of programs from accessing the internet. The runDLL errors are:
error loading C:\windows\system32\buvujano.dll
error loading C:\windows\system32\gurelido.dll
The specified module could not be found.

The two infections that AVG found so far were:
trojan.virtumonde
trojanhorseVundo.EL

I also loaded free trial versions of PCdoctor and cyber-something or other that would not leave me alone after I wouldn't pay....
I haven't upgraded either of these (cyber-something got uninstalled), I'm waiting on my friend to come over tomorrow with his credit card. Both programs scanned and found a list of infections, but of course wanted me to register before it would fix them.

I'm stuck. Are there other options?

I do not recommend that you have more than one anti virus product installed and running on your computer at a time. The reason for this is that if both products have their automatic (Real-Time) protection switched on, then those products which do not encrypt the virus strings within them can cause other anti virus products to cause "false alarms". It can also lead to a clash as both products fight for access to files which are opened again this is the resident/automatic protection. In general terms, the two programs may conflict and cause:
1) False Alarms: When the anti virus software tells you that your PC has a virus when it actually doesn't.
2) System Performance Problems: Your system may lock up due to both products attempting to access the same file at the same time.
Therefore please go to add/remove in the control panel and remove any extra ones. You may have to disable them to uninstall. I would like to know which ones you have used.




Please download ATF Cleaner by Atribune & save it to your desktop.
  • Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose: Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.

Please download Malwarebytes Anti-Malware (v1.34) and save it to your desktop.

If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

Thanks Chewy, that looks like it will do the trick. I'll keep you posted if anything comes up.

Would you at least run another scan with MBAM to see if it returns an all clear, there may even be something MBAM misses.

It's better to err on the side of caution
